Public bug reported: 1) The release of Ubuntu using Ubuntu 12.10 64-bit.
2) The version of the package used linux-image-3.5.0-26-generic 3) What you expected to happen Audio being played smoothly without breaks and cracking sound. 4) What happened instead After upgrading to Linux kernel 3.5.0-26-generic, one of my USB DAC (Digital Audio Codec) suddenly started to produce constently discontinous sound. Whenever there is audio being played by the system, the outcome would be always accompany with regular, stable, 5 to 6 times per second breaks. Both the system sound and songs from media player failed. One of my USB DAC works under Asynchronous Mode (USB device host clock), the other one works under Synchronous Mode (Motherboard host clock). The Synchronous one worked as usual after the updrade, while the Asynchronous one did not. I downgraded the package to the previous 3.5.0-26-generic, then everything went back to normal. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: quantal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1136110 Title: Asynchronous USB DAC cracking sound in Linux kernel 3.5.0.26 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1136110/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
